Types with inaccessible destructors may still be freed by Rust

1

## Expected Behavior Refuse to allow freeing C++ objects with inaccessible destructors. Constructible C++ classes with non-public destructors are uncommon in my experience, but the ones that do exist are...

C++ methods with reference qualifiers result in non-compiling wrappers

1

## Expected Behavior Either ignore them or generate usable wrappers. I don't see a problem with ref-qualified methods, but rvalue-ref-qualified ones should probably be ignored because there's no good Rust...

Explicitly defaulted default/copy/move constructors are treated as present

2

## Expected Behavior They should be handled the same as implicitly defaulted constructors (aka no user-defined ones). This means they may be deleted or present, depending on the members and...

Member initializers are ignored when checking for default constructors

2

## Expected Behavior If members of types without default constructors have default initializers, they should not prevent treating a class as though it has a default constructor, when the default...

## Expected Behavior Acknowledge the existence of base classes with no member variables. They may have member functions and/or special member functions. ## Actual Behavior bindgen fails to create the...

`shared_ptr<const int>` leads to C++ code that doesn't compile

4

## Expected Behavior Emit bindings that work. dtolnay/cxx#1006 says that inserting a typedef results in `cxx::bridge` handling it already. dtolnay/cxx#850 talks about making it easier. dtolnay/cxx#537 and dtolnay/cxx#885 have some...

Information discarded by bindgen which we need (tracker bug)

6

bindgen doesn't pass on _quite_ all the information we need in order to be able to generate autocxx bindings. Options in the future might be to fork bindgen, ask _very_...

#ifdef support

3

It's my intention that we can support Rust compile-time feature enablement based on C++ macros. Where users are using our `build.rs` support in https://github.com/google/autocxx/tree/main/gen/build this should really be pretty trivial...

Remove strum_macros and use full #[derive(Debug)]

2

Simpler but the debug output is incomprehensibly huge. We need to wrap all `syn` things in a newtype wrapper which outputs more concise debug output.
